Application August 21,

, 4 Claims. My invention relates to a new and improved slide drawerconstruction.

One of the objects of my invention is to provide improved slide meansfor guiding and supporting drawers or shelves in desks, refrigerators,cabinets and other articles of furniture.

Another object of my invention is to provide a simple and strongconstruction, in which the track members are properly supported so as toprevent sagging, so that the drawer can be subjected to rough usagewithout injuring the device.

Another object of my invention is to provide an improved device of thistype, having antifriction members such as balls, rolls and the like.

Other objects of my invention will be set forth in the followingdescription and drawings which illustrate a preferred embodimentthereof, it being understood that the above statements of the objects ofmy invention is intended to generally explain.- the same withoutlimiting it in any manner.

' Fig. 1 is a top plan view of the improved device, certain of the partsbeing represented as being partially broken away, in order to more fullyillustrate the construction.

Fig. 8 is a perspective view of the drawer track member.

Fig. 9 is a sectional view showing a modification of the invention asapplied to a drawer which is located underneath a bench or the like.

Fig. 10 is a transverse sectional view, partially 45 in elevation,showing another embodiment of the invention.

Fig. 11 -is a plan view showing the improvements applied to arefrigerator.

Fig. 12 is a sectional view on the line I2-l2 of Fig. 11.

Fig. 13 is a sectional view on the line I3-I3 of Fig. 12.

Referring to Fig. 6, the device includes a fixed track member I, itbeing understood that the device has one of such fixed track members,and

1934, Serial No. 740,763

one or more movable track members, at each side of the drawer or thelike.

For convenience it is to be assumed that the drawer slides in ahorizontal plane.

The fixed track member I is provided with a 5 vertical web 2, whichisprovided with holes 3, through which screws S or other fastening memberscan be inserted in order to secure the fixed track members 2, to thefixed walls of the desk or the like.

The heads of the fastening members are countersunk in the holes 3. Thefixed track member is-provided with upper and bottom walls 4 and 4a, andsaid walls are provided with grooved portions 5 and 511.

At its rear end, the fixed track member I is provided with a horizontalstop-pin 6 and the top wall 4 is provided at its front end with avertical stop pin 7. The stop pins 6 and 1 may be secured by drive-fits,or in any other suitable 20 manner. I

The extension slide 8 has a substantially U- shaped cross section, sothat it has a vertical wall 9, a top wall I0 and a bottom wall Illa. Atits rear end, the vertical wall 9 is provided with 25 a recess II, whosewall is adapted to abut the stop pin 6, when the drawer is in its innerposition. The inner movable track member 8 is provided with one or moreanti-friction balls B. These balls are provided with pin-shafts I2 and30 I2a, which pass through the centers of said balls. Said pin shafts I2and I2a are located in recessed portions I4 of the top wall I0, andrecessed portions I 4a of the bottom wall Illa.

I have shown two such balls B, but I could 3 use only one ball, or morethan two of such balls.

The halls B roll in the grooves 5 and 5a.

Each member 8 has horizontal flanges F, in which a. rubber wheel orroller R is turnably mounted, by means of a suitable pin-shaft, as 40shown at the left-hand side of Fig. 3.

The vertical wall 9 is provided with a cut-out C, through which saidrubber wheel or roller projects, so that it makes rolling contact withthe vertical wall 2 of the fixed track member I.

Each drawer track member 20 is provided with a U-shaped flange 2| whichis welded or otherwise suitably secured thereto. The top and bottomwalls of said U-shaped flange 2| are provided with grooves 22 and 22a.The balls B roll in said grooves 22 and 22a. The drawer track member 20is also provided with vertical pins 22b .which enter suitable holes orrecesses which are provided at the front part of the bottom surface 01'the drawer or shelf.

The member 20 is also provided with a stop flange 23, having a shoulder24' which abuts with the iront stop pin I. o! the fixed track member,when the drawer is pulled out.

When the drawer D is pulled out. the extension slide members 8 anddrawer track members 2 0 are simultaneously withdrawn from the housing,but the outer drawer-track member 20 moves in advance of the extensionslide 8. This is caused by the wheel R, which contacts with the verticalwebs of fixed track members I and drawer track 20. Said wheel R isturned by drawer track member 20 when this is pulled out, and therolling contact between wheel R and web 2 of fixed track member I causesextension slide member 8 to move outwardly, and to lag behind drawertrack member 20.

Referringto Fig. 3, it will be noted that. the portions 511. of thefixed track members rest directly upon the bottom of the casing 25, inwhich the drawer D is mounted.

Hence the screws S, which pass through the holes 3, do not support theweight of the tracks in any manner, as said weight is fully taken up bythe bottom of the casing. Said screws S merely hold the fixed trackmembers laterally against the vertical walls of the casing 25, so thatlittle or no strain is imposed upon said screws S. The wheel R islocated directly between a of superposed anti-friction members B, butthis rela-.

, tion is not necessary.

, of said drawer, and the drawer can then be moved away from the casingand the track members.

The same essential arrangement is shown' in Fig. 9, save that the drawertrack members 20 have lateral-flanges at their tops and bottoms.

Fig. 10 shows the track=members located below the drawer D, so that thefixed track-members rest upon the bottom of the casing. This viewclearly shows the openings in the bottom of the drawer D, said openingbeing provided with metal liners L. The parts which have been previouslymentioned are shaped somewhat differently, in order to locate them belowthe bottom of the drawer. I

Fig. 11 shows a casing 25 which forms part of a refrigerator. The drawerD may have a mesh bottom De.

As shown in Figs. 7 and 11, the extension slides 8 may be provided withturnable rollers I00, each having a concave wall, on which the convexsurfaces of grooves 22 and 22a. can slide while aid rollers I00 turn. Asshown in Figs. 11 and 12, the shapes of drawer-supporting track members26 are modified. The fixed track members are provided with sleeves I0 Iinto whic-h'pins I62 enter, said pins I02 being fixed to the walls ofcasing 25. Set-screws I03 hold sleeves I it! to pins I02. These pins andsleeves provide a strong and rigid support, which prevents sagg ng.

In the modification of Figs. 3 and 10, i have shown the fixed guide ortrack means abutting the bottom of the casing. This is not absolutelyessential, as a. slight spacing would be sufilcient to preventsubstantial sagging. Likewise,

the anti-friction devices may be located either at the top or bottom ormember 6, instead of at both top and bottom, as this wo'eld be a clearequivalent.

I have shown preferred embodiments of my invention, but it is clear thatnumerous changes and omissions could be made without departing from itsspirit.

I claim: 1. A slidable drawer device comprising a casing, fixed trackmeans connected to the casing,

extension slide means movable relative to and guided by said fixed trackmeans, and drawer track means connected to said drawer, said extensionslide means being located between the fixed means and the drawer trackmeans, said fixed track means and said extension slide means havingcooperating vertical webs, the extension slide means having roller meansin rollingcontact with both said webs.

2. In a slide drawer device, an extension slide having a vertical web,and roller means con nected to said slide and projecting through saidvertical web, said roller means being mounted to turn around a verticaiaxis.

3. A slidable drawer device comprising a casing, fixed track meansconnected to said casing and having upper and lower walls provided withgrooves, an extension slide member having upper and lower walls whichare provided with ntitriction means which move in said grooves, saidextension slide means having a roller turnably connected thereto, and adrawer track member having grooves whose walls are located between andcontact with said anti-friction means, the drawer being connected tosaid drawer track member. said fixed track means and said drawer trackmember having vertical flanges which contact with said roller, so thatsaid roller is turned when the drawer is pulled out of the casing, andthe turning of the roller causes the first slide to move outwardly.

4. A slidable drawer device, comprising a cas ing, fixed track meansconnected to said casin and having upper and lower walls provided withgrooves, an extension slide member having upper and lower walls whichare provided antifriction means which move in said grooves, said firstslide having a roller turnably connected thereto, and a drawer trackmember having grooves whose walls are. located between and contact withsaid anti-friction means, the drawer being connected to said drawertrack member, said fixed track means and said drawer track member havingverticai flanges both of which being connected to said casing by'pin andsleeve connections.
